My mother died about a year ago. My father is currently living alone but his house is on the market. I'm not too crazy about his real estate agent due to several incidents but my father insists on using him as he is also a neighbor. Recently, my father dropped the price of his house several times each time a large price drop. He has no other savings so his house will be his only income. I think he he's making foolish financial decisions. My sister offered to take him in even if the house didn't sell right away but he doesn't want to leave without selling it. He doesn't discuss any of this with his children. I found out about these price drops by looking online. I think he is loosing significant amounts of money but he doesn't want to be bothered. Can I have him declared incompetent? Any suggestions. He doesn't want to talk about it or gets mad when I try to discuss with him.
